DOC: Add

[antznette1]

• Added a concise “Quick start (pip + meson, editable)” section to
  doc/source/development/contributing_environment.rst.
• Included Windows-specific guidance (VS Build Tools, PATH, long paths, execution policy, and Meson editable verbosity).
• Provided a “Next steps” sanity check and focused test command.

Motivation

• Streamlines the dev install path using pip + Meson (PEP 517), which auto-rebuilds C/Cython on import.
• Addresses common Windows pitfalls that frequently block first-time contributors.

Key changes

• New quick-start code block for editable install:
  • git fetch upstream --tags
  • python -m pip install -ve . --no-build-isolation -Ceditable-verbose=true
  • Optional -Cbuilddir=".meson_build" and -Csetup-args="-Dbuildtype=debug" tips

Windows notes: Build Tools, long paths, execution policy, and MESONPY_EDITABLE_VERBOSE.

Validation steps

• Local editable install built successfully on Windows (3.12, MSVC, Meson).
• Sphinx html docs built locally; the new section renders correctly in:
  • doc/build/html/development/contributing_environment.html

Please note that the change is purely documentation; no API or behavior changes.
